ridgeway deeps mine block caving

Ridgeway Deeps is a block cave (BC) located down dip of the operating Ridgeway sublevel cave (SLC) mine. The BC is located approximately 210 m vertically below the lowest SLC level and approximately 1100 m below surface. Due to the mine layout containing a number of common pieces of key infrastructure the activities of both were interlinked. When investigating project construction options for ...

Key geotechnical knowledge and practical mine planning ...

The success of that mine led to a significant expansion into block caving operations, first at Ridgeway Deeps, and then to the now established Cadia East operations. What makes Cadia unique is the high-stress, hard rock mining conditions combined with the ability to maximise investor returns through the use of very high lift heights at depths of between 1,200 to 1,400 m. Over the last decade ...

Full-scale Flow Marker Experiments at the Ridgeway Deeps ...

09/05/2016  Initial marker experiments were undertaken in the Ridgeway sublevel cave (RW) (2002), and subsequently at Ridgeway Deeps (RWD) (2008) and Cadia East PC1 (CEPC1) (2012) block caves. Over 25 000 markers have been installed at the three caving operations to date (approximately 20 000, 3000 and 2500 for RW, RWD and CEPC1 respectively). These experiments aimed to quantify and

Ridgeway gold mine Report Wood Mackenzie

Ridgeway is an underground copper/gold mine which is located 3km north west of Newcrest's Cadia Hill open pit mine. The mine is undergoing a transition to block caving which will see production levels reach 6Mt/a ore by 2012. In October 2012 Newcrest indicated in a corporate presentation that ore feed from Ridgeway underground mine will cease in 2015 with the depletion of Lift 1. Stated ...

Mining Methods: Block Caving Geology for Investors

15/02/2021  In some mines, there are multiple block caving events, such as at the Ridgeway mine in Australia, when the initial block cave was depleted they went deep (1100 metres below surface) for their second block cave. In other cases such as Cadia, Palabora and Chuquicamata block caving was the solution to extending mine life when the open pit resources ran out. The Globe Miami mine is

Block caving - QueensMineDesignWiki

Block caving is an underground mining method that uses gravity to exploit massive, steeply dipping ore bodies located at depth. These ore bodies are generally low grade in nature and are too deep to be extracted through open pit mining. The technique is commonly used to extract low grade copper, copper-gold, iron and molybdenum ores although there are other applications. Due to the low cost ...

Cave Tracker: Safe and performing block cave mines

Block caving as a mining method is a risky enterprise given the lack of insight into the environment in which the mine must operate. Block caving relies on fragmentation and forces of gravity to ‘cave’ the fragmented ore to draw points built deep underground, from where it is collected and taken away for processing. Mine operators cannot see what is happening in the fragmented body of ore ...
